Application filed February 1, 1924.

To all whom t may Concern:

Be it known that I, Ln ROY I-l. finestrino.

a citizen of the United States of America,

and a resident of the city of New Yori-1, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Dumb-VVaiter. of which the following is a description.

My invention relates to dumb-waiters and particularly has in view the provision of a dumb-waiter having a lining or protective covering of sheet metal.

The desirability of a lining in a dumbwaiter is universally recognized in the trade and various attempts have been made to provide the lining without presenting raw edges on which the hands of a person using the dumb-waiter might be injured and without lessening the free clearance afforded in the elevator well for the dumb-waiter and without affording a possible obstruction to the placing of goods on the dumb-waiter.

The general object of my invention is to provide a securing means for holding the edge of the sheet metal lining and to so dispose said lining that no raw edges will be presented at the front and without returning the lining at the outside of the dumb-waiter, whereby the lining will afford 30 no portion on which the articles being entered in the dumb-waiter Could catch.

The means whereby the above object is attained will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of examples of the invention.

Figure 1 is a vertical section of a dumbwaiter having a lining applied thereto and secured at its front edge portion in accordance with my invention;

Figure 2 is an enlarged fragmentary horizontal section in a plane indicated by the line 2-2 of Figure 1';

Figure 3 is a view similar to Figure 2 with a slight modification in the mode of securing the edge of the lining;

Figure 4 is a view similar to Figures 2 and 3 but illustrating a further modification.

In carrying out my invention in practice, the dumb-waiter is constructed generally in the usual manner, the numeral 11 indicating the customary shelf. The front 12 of Serial No. 689,960.

the dumb-waiter is open as usual for the free entrance and ren'ioval of goods. The numeral 13 indicates the usual eye on the top of the dumb-waiter for the connection of a hoist rope.

In accordance with my invention I provide a lining 14 covering the inner surface of the bacl of the dumb-waiter and extending over the bottom as at 15 and the under side of the top as at 16. The material of the lining is carried at the top upwardly front of the top frame of the dumb-waiter as at 17 and then carried rearwardly to cover the top as at 187 the free edge portion being turned downwardly against the back of the top frame as at 19.

In the form shown in Figure 2 the lining 14 at the sides 2O of the dumb-waiter is made to terminate short of the front edge 21 of the sides of the dumb-waiter. sides 22 of the dumb-waiter at the inner surfaces, I form, in accordance with my invention, vertical grooves or kerfs, inward from the edge 21, and the terminal front edge portions 24 of the sides 20 of the lining are bent laterally outward at an angle. In Figure 2 said edge terminal portion 24 is at right angles to the plane of the dumb-waiter side. In Figure 8 the side 122 of the dumbwaiter has an oblique or undercut vertical slot or lzerf 123 and the front edge portion 124 of the lining material 120 applied to the side 122 is return bent at an acute angle to enter said oblique groove 123.

In Figure 4 the lining 220 is carried to the front edge of the side 222 of the dumbwaiter and directed laterally outward to partially cover said outer edge. A vertical groove or lerf 224 is formed in the side 222 extending from the front edge thereof and the terminal edge portion 228 of lining 220 is bent into said groove to lie parallel or approximately so with the inner surface of the dumb-waiter side 222.

By thus entering the terminal edge portion of the lining into grooves in the sides of the dumb-waiter, the lining is effectively secured in a manner that it cannot possibly engage goods being entered in the dumbwaiter and cannot afford injury to the hands of a person using the dumb-waiter. Moreover, the secure fastening of the lining is effected without bending the lining over the front edge of the dumb-waiter sides and returning it at the outer side surfaces of the In the board dui'nb-'Waiter sides to lessen the clearance space in the elevator well.

Having thus described my invention, l claim:

l. A dumb-Waiter open at the front and sheet metal lining material applied'thereto and extending at the sides of The dumb- Waiter, the sides of the lining terminating at the front edges short of the front edges of the sides of the dumb-Waiter, said dumb- Waiter having vertical grooves in the sides thereof` inward from the front edges of said sides, and said lining covering the sides of the dumb-Waiter having the terminal front edge portions thereof bent laterally out- Ward into said grooves to securely hold the lining Without presenting an exposed edge portion.l

2. A dumb-Waiter having an open front and sheet metal lining material covering the sides thereof, the sides of the dumb-Waiter having vertical grooves and the material of minimi the lining being bent laterally outward into said grooves. Y Y

3. A dumb-Waiter having an open front, a sheet metal lining, said lining covering the bottom, the under surface of the top, and the back of the dumb-Waiter, said material extending over the sides but terminating short of the front edges of the sides of the dumb- Waiter, the sides of the dumb-Waiter having vertical grooves and the forward edges of the sides oi" the lining being bentinto said grooves, the material at the under side of the top being carried upwardly at thefront of the dumb-Waiter and over the top to the back of the dumb-Waiter.

4. A dumb-Waiter having an open front and sheet metal lining material applied to the sides ofsaid dumb-Waiter, said sides having vertical grooves and the material of the lining at its front edge portion being bent into said grooves.
